Javascript: Open PDF in new tab from byte array

javascriptjqueryangularjspdfbytearray

提问by Jeremy Wagner

I'm using AngularJS with an HTTP resource to call an external API and my response is a byte array. I need to turn this byte array into a PDF in a new window. I haven't seen any very good solutions on here that work cross browser or that are pure javascript. Is there a way to do this?

我使用带有 HTTP 资源的 AngularJS 来调用外部 API,我的响应是一个字节数组。我需要在新窗口中将此字节数组转换为 PDF。我还没有在这里看到任何非常好的解决方案,可以跨浏览器工作或纯 javascript。有没有办法做到这一点?

Here is my code:

这是我的代码:

Javascript

Javascript

Document.preview({id: $scope.order.id}, function(data){

    // Open PDF Here
    var file = new Blob([data], {type: 'application/pdf'});
    var fileURL = URL.createObjectURL(file);
    window.open(fileURL);

});

You would need to pass the responseType in your service call

您需要在服务调用中传递 responseType

$http.post('/Service-URL', dataTO, {responseType: 'arraybuffer'});

then in the success of your data call this should open up pdf in a new window:-

然后在您的数据调用成功后,这应该在新窗口中打开 pdf:-

    getDocument()
        .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            var fileURL = URL.createObjectURL(file);
            window.open(fileURL);
    })

If anyone still looks for that, here is what I'm doing (and working) :

如果有人仍然在寻找,这就是我正在做的(和工作的):

var pdfAsDataUri = "data:application/pdf;base64,"+byteArray;
window.open(pdfAsDataUri);

Where byteArray is the data you receive. It's maybe not a nice solution (byte array is visible in the URL), but it works...

其中 byteArray 是您收到的数据。这可能不是一个好的解决方案(字节数组在 URL 中可见),但它有效......
